When one mentions the term erectile dysfunction drug, there are 3 names which spring to mind: Viagra, Cialis and Levitra. All work in a similar function, but there are differences apart from simply coming from different manufacturers of erectile dysfunction drug.

Viagra
Viagra is the commercial brand name for sildenafil citrate, manufactured by Pfizer. Approved in 1998 by the FDA for the treatment of erectile dysfunction, it has been used safely and with good results by millions of men since. This erectile dysfunction drug is taken in tablet form.

Erections occur when stimulation results in nerve signals releasing hormones that cause the smooth muscle tissue in the penis to relax and fill with blood. Viagra enhances this natural process when there is some condition preventing it from occurring naturally. There is a chemical which naturally allows blood to flow out of the penis- Viagra essentially blocks this. An increase in blood retention results in a stiffer, harder penis- which is obviously what this erectile dysfunction drug is most well known for.

Recent clinical erectile dysfunction medicine studies show that nearly 90% of those using Viagra properly report improved ability to consistently achieve and sustain erection. For the majority, Viagra begins working in about thirty minutes, and may continue to be effective for up to 4 hours. Taking into consideration that the average sexual encounter lasts thirty minutes, this allows for complete satisfaction for the majority of user's of this erectile dysfunction drug.

Cialis

Produced by the Eli Lilly Company, Cialis is the commercial brand name for the erectile dysfunction drug tadalafil. Cialis works in a way similar to Viagra, but the dosage is quite varied. Typical prescribed dosages will vary from patient to patient, with most taking either 5 mg, 10 mg or 20 mg. In contrast the average Viagra dosages are much higher - 25 mg, 50mg or even 100mg.

Like Viagra, Cialis works in about thirty minutes, but the effects may last as long as 36 hours. Clinical studies show that this erectile dysfunction drug is effective for about 78% of those who try it. In other words those who chose Cialis are trading off effectiveness for longer lasting effects.

Levitra

Levitra is manufactured by Bayer Pharmaceuticals and is commercially distributed by GlaxoSmithKline and Schering-Plough. Levitra is a brand name for the erectile dysfunction drug vardenafil. As is the case with Viagra and Cialis, Levitra works by reducing blood flow out of the penis. Studies show this erectile dysfunction drug to be approximately 80% effective. Effects should set in within 1 hour. As is the case with Viagra, Levitra works for approximately four hours.

Conclusion:

All three erectile dysfunction drugs work in a similar way. Which one is best for an individual patient will depend on your own circumstances and condition. These will include medical history, symptoms or diagnosis for the underlying cause of erectile dysfunction, age and general health.

Particularly those that are taking other medications, such as nitrate-based heart medications for example, should avoid taking Viagra. All three erectile dysfunction drugs have a long list of potential drug interactions that need to be thoroughly investigated before beginning a treatment. All erectile dysfunction drug's interfere with blood pressure.

It is always advisable to consult a physician before you begin taking any form of erectile dysfunction drug.
